Module Supersized 2
I include with this template a module "supersized2" to display the full screen slideshow. There are a version for Joomla 1.5 / 2.5 and 3.X.
I remove a lot of options to keep only the essential : you can choose to show or hide the thumbnail when you hide the content box.
Install the module and choose the position "supersized"
This is a screenshot with all the options.
Note : you can display a maximum of 18 images (I cropped the screenshot).
